Unsupervised children drying or warming fabric in a microwave caused a fire that displaced 50 people in an apartment fire this weekend, fire officials say.

It happened at 6:30 a.m. Sunday morning at a 24-unit complex at 1686 Shawano Ave.

People were seen hanging from second-story windows to escape flames, and firefighters ran from apartment to apartment banging on doors and breaking them down to make sure no one was inside.

Eight people were injured in the blaze.

Investigators determined the fire was accidental, due to misuse of an appliance. Officials urged residents not to use microwave ovens to warm clothing or towels. They also recommended apartment tenants get renters insurance and check their smoke detectors regularly.
